vApplication filed May 26, 1916. Serial N o. 99,989.

Be it known-that I, FRANK J. HRUSKA, a citizen of the United States,residing at Cedar Rapids, in the county of Linn and State of Iowa, haveinvented new and useful Improvements in Binders, of which the followingis a specification.

This invention relates to binders and con-y sists in certainimprovements in the condescribed and pointed out in the claims.A

` More particularly the invention is directed to binder trays forhandling leaves which are used in connection with bookkeeping machines.The device while not limited to this use is designed with this in view.

The invention is illustrated in the accomy panying drawings as followsFlgure 1 shows a perspective view of the b inder tray with the leaves inopen posi-` Fig. 2 the binder .tray with the leaves closed.

Fig. 3 a plan view of the binder tray.

Fig. 4 a section on the line 4 4 in Fig. 3.

Fig. 5 a section of a fragment of the tray on the line 5-.5 in Fig. '3.

The base of the tray is made up of the strips 1 1 preferably. of Wood.Angle irons 2 are arranged along the outer edges of these strips, theinner legs of the angle irons extending over upon the top face of thestrips. Plates 3 3 are arranged along the inner edges of the strips 1.These are spaced apart forming a slot in the base. The strips 1, aresecured together by the end pieces 5.

A screw 6 is rotatively mounted in the end pieces 5 and locked againstend movement relatively thereto. The screw has the threads at itsopposite ends oppositely support and guide for the clamping bars. Theclamping bars have the upturned ends 11 and the backing plates 12 arepivotally mounted by means of pins 13 between the upturned ends 11, theends of the plates being flanged or turned backwardly tofacilihereinafter fully tate this mounting. Slots 14 are arranged in theplates 12 near the bottom of the flanged ends and stop pins 15 extendthrough the upturned endsy 11 and int'o the slots and form stopslimiting the pivotal movement of the backing plates 12.

Guide rods 16 extend from end to end of the binder. They extend throughslots 17 in the upwardly extending plates 18, these plates being securedbetween the end pieces 5 and the ends of the strips 1. The rods 16 havereduced ends forming the shoulders 16EL which engage the plate and thumbscrews 19 are arranged in the outer ends of the rods. By loosening thesethumb screws the rods may be moved laterally in the slots 17 and thenlocked in adjustment by kthe thumb screws. The rods 16 are designed toenter the ordinary notches 20 in the leaves 21 and thus hold the leavesin register.

In order to facilitate the use of the device wherev the leaves are beingwithdrawn and replaced, it is desirable to provide a guide as 22 alongone side of the binder against which the leaves may be thrown inreturning them to the binder. This may be accomplished if the clamp isopen at the side opposite the guide 22, or at least open throughout thegreater part of the side of the clamp as this will permit of throwing ordelivering the leaves sidewise into the clamp, the side rod forming astopagainst which the leaves are brought to rest. The

'rod 22 has its ends bent downwardly eX- tending into' the base and arethere secured. This rod is at a height to engage the edge and thus stopthe side movement of a leaf as it-is being returned so that it willsettle infits proper position with its notch or notches on the rod 16.

It will be observed that the pivots formed by the pins 13 are below thecenters of the backing plates so that when the binder'k is opened theparts naturally tilt so as to give the leaves their proper slant andmake themreadily accessible as clearly shown in Fig. 1. The opening maybe made to any extent that may be desired. When the parts are closed andthe backing plates clamped against the leaves they automatically bringthe leaves into parallel relation and bring the leaves at the top edgesinto close contact.

By making both clamping bars movable and mounting them on the screw withthe i ra right and left pitch the Vbars aremoved equally in bothdirectionsand consequently the leaf body is maintained in a centralposition on the base of the binder. Thus the weight is always centrallylocated and the stability of the binder whenbeing used is thusincreased.

Binders of. this type are opened so as to loosen the leaves in orderthat they maybe freely removed and returned to the binder and there is atendency of the leaves to slide out of place. To obviate this a surface28 of corduroy is arrangedon the top of the base forming a backing as itwere for the binder. Any roughened vsurface such as velvet or similarmaterial may be used but corduroy is preferred as it presents pronouncedribs, these ribs being arranged transversely of the base. This roughenedsurface or the ribs of the fabricengage the edges of the leaves and thusprevent theslipping down of the leaves when the binder is open. Thealined ribs ot the corduroy also tend to maintain the sheets inalinement. The corduroy should be arranged at such a distance from therods 15 as to receive the weight of the leaves.

What l claim asnew is t 1. ln a binder tray, the combination of a base;a screw mounted on the base, the threads et the screw being oppositelypitched at the opposite ends; a clamping bar mounted on each end of thescrew; and a. backing plate pivotally mounted on one of said clampingbars, the axis of the pivot being between the top. and bottom of theplate. y l 2. In a. binder tray, they combination of a base; a screwmounted on the base, the threads of the screw being oppositely pitchedat the opposite ends; a clamping bar mounted on each end of the screw;and a backin plate pivotally mounted on each of said c amping bars, theaxis of the pivots being between the top and bottom of the plates. y

3. ln a binder tray, the combination of a base; a` screw mounted on thebase', the

threads of the screw being oppositely pitched at the opposite ends; aclanupm` bar mountedon each end of ,the screw; an

on the base and a backing plate pivotally mounted on one side of saidclamping; below the center of the late.

4c. ln a binder tray, the combination of a base; a screw mounted in thebase; a clam ing bar mounted on the screw; and a baciing plate pivotallymounted on the clamping bar, the axis of the pivot being between the topand bottom of the plate.

5. ln a binder tray, the .combination of a base having a longitudinalslot` therein; a screw mounted on the base in the slot, the threads ofthe screw being oppositely pitched at opposite ends; nuts on the screw;clamping bars mounted on the nuts, the nuts riding on thescrews forming;guides for the clamping bars; said clamping bars having upturned ends;mounted between the 11p-turned ends, the axis of the'pivots beingbetween the tops and bottoms of the platesy and below the centerthereof; and stops limiting the pivotal movement of the plates.

6. ln a binder tray, the combination ot a base; a clamp\mounted on thebase; and a.

tranversely adjustable I@guide rod mounted adapted to engage notches inleaves in theclamp.
